Why can’t they “Go back”? — A multi-group comparative analysis of pre-service teachers’ hometown return intention in local universities based on latent profile analysis

The high-quality development of rural education urgently requires strengthening the supply of outstanding rural teachers. Based on Social Cognitive Career Theory (SCCT), a survey of 6,546 teacher education students from local universities in Heilongjiang Province revealed that th...

Exploring the Molecular Mechanism of Ganoderic Acid B for Insomnia Based on Metabolomics, Network Pharmacology, Molecular Docking, and Experimental Validation

Abstract Objective: Ganoderma lucidum, a fungus of the genus Ganoderma in the family Polyporaceae, is often used in traditional medicine for the treatment of insomnia and amnesia, etc. Ganoderic acid B, a characteristic lanostane-type triterpenoid isolated from Ganoderma lucidum,...

Height-threshold-dependent estimates of forest gap characteristics, spatial patterns, and dynamics: Evidence from multi-temporal UAV–LiDAR

Forest gaps record disturbance, regeneration, and canopy structural change, yet estimates of gap closure depend strongly on the height threshold used to define when a gap is considered closed. This issue is particularly relevant for three-dimensional LiDAR analyses, where gap str...

SPACES OF COMPACT OPEN SUBGROUPS AND OPEN MORPHISMS

Abstract For a morphism whose domain is a totally disconnected locally compact group, the openness test of Cowling, Hofmann and Morris [‘Open mappings of locally compact groups’, J. Group Theory 27 (6) (2024), 1143–1149] can be stated in terms of compact open subgroups. We use th...

Differentiation of plant adaptive strategies on the Jingpo Lake lava plateau: a comparison of leaf and absorptive root functional trait spectra across different life forms

Focusing on the highly heterogeneous habitat of the Jingpo Lake lava plateau, this study quantified 24 above- and below-ground functional traits across 12 dominant species. Transcending the conventional single-organ perspective, we investigated whether environmental stress drives...
